a uniform metre ruler PQ is in equilibrium.
the distance PQ is 100cm
the mass of the metre ruler is 0.12kg and its weight is W.
point P is 10cm from the pivot and has a weight of 0.5N hanging from it. Point Q has a force going upwards on it.

Question: on the fig. draw
1. an arrow to shoe force W acting in PQ at the centre of mass
2. an arrow to show the force R acting at the pivot.

Answer:

W located in the middle of the ruler, R located at 10cm from the pivot point.

See the attached image.

Explanation:

To solve this problem we have to perform a free body diagram symbolizing each of the forces that act on the bar in balance.

In the attached image we can see the free body diagram.
